I don't know what was wrong with my device or maybe it was with my internet. I came back home and saw that the synchronization was finished. So, I wanted to give it a break because the laptop has been turned on for over a week now. But when I started the node again, it couldn't connect to the peers anymore. Maybe it was my internet issues but I was able to access the internet from my laptop. But the wallet finally fully synchronized again. Now my question is, what should I post tomorrow?

No, it's usually faster to sync than mainnet at least from my own experience (never timed it but as far as I remember you can sync within a few hours)
I tried to sync it like 5 to 10 minutes and even in early years, syncing speed is not too fast. 
Really want to participate on this one but I only have a computer on my work and the laptop in my house is unreliable because it's an archaic Lenovo model. What does running a bitcoin node do? I'm curious about that because I want to explore the old stuff that other people used to do with bitcoin. Does running a node means that you're like a validator for the network?
Bitcoin is a blockchain. The native token of this blockchain is BTC.
When you press the "send" button on your wallet, or when you watch your balance and the balance is updated, the wallets must be connected to a "provider" of this information.
What do they do?
1. They connect with the rest of the nodes and they exchange block and transaction info to keep the whole network up to date.
2. They keep a local copy of the blockchain so they can't be "scammed" by fake transactions or by people who pretend to own BTC that they don't actually own.
3. They validate the validity of every transaction and every block
So why should you run a node?
1. So as you have the copy of the blockchain
2. So as you can use it to communicate with the rest of the network
3. So as you can validate yourself every transaction and be helpful for the network
4. For privacy reasons. You can't broadcast a transaction, or update the balance without using a node. If you use another person's node, then they will know everything about this transaction and the addresses that you use. So, using your own node is an easy way to fix it.
I can't stress enough how important nodes are for Bitcoin. They are the heart of the whole network. Miners too, of course, but nodes are easier to run and yet, not too many people run them.

Wow, the days passed so fast. Thank you for this learning opportunity! Throughout all these years I'm involved in cryptocurrencies, I had never installed Bitcoin Core, at least the recent years. I had probably installed it when I first learned about Bitcoin somewhere in 2014, but I highly doubt if I ever got it fully synced and running. I'll keep in synced and running whenever my computer is enabled. It has been a great experience, thank you once again for the opportunity!

Exactly. By running a node, you increase the strength of the bitcoin network and make it harder for anyone to deploy a fake blockchain and transaction history.

I wasn't home yesterday, so I couldn't post my progress for day 14. Here it is. Progress kinda slow, I'm almost close to sync. Can you please update the OP. I will keep running it until fully sync.DAY 14 progress: 85% sync

I have a question. Does syncing a Testnet Bitcoin Core node take a similar time like on Main net?
No, it's usually faster to sync than mainnet at least from my own experience (never timed it but as far as I remember you can sync within a few hours). The Testnet3 blockchain has way more blocks than mainnet but is significantly smaller compared to mainnet because testnet blocks normally contain only a few transactions (not sure if there's a testnet block that's actually full to the limit). Validation of testnet blocks is therefore notably faster than for filled mainnet blocks.

Don’t let the your screen sleep at all. Mine is all set to “never”, and no mater how idle my laptop is, it never sleeps until it is completely dead. When you’re doing then you can turn it back off to what you had.
Thanks, oktana for your advice. I changed the settings yesterday and now it's been over 24 hours. My device didn't get into sleep mode anymore. Which means your advice worked well.
Cheers mate.

Unfortunately, I forgot to boost my internet speed last night and it downloaded only 16 GB of blocks at night instead of 64 GB and my internet wasn't stable since yesterday night. But, my progress isn't bad though. I am only 25 weeks behind at this moment.
How do you mean to boost your internet, Is it like a software you use to achieve that? I do run into internet issues too and sometimes I’m forced to restart my internet. Just looking at your progress, I can tell your internet is great because I’m at DAY 9 but your gap is huge.
