I prefer to say "Life is a challenge".
Challenges are an inseparable part of life, people who are starting a career or who have reached a level of success are never free from challenges.
Every challenge that can be overcome will give you confidence that you will be able to win an even bigger challenge, enjoy all of it, challenges or puzzles as the term you use here can shape your character even better.
That’s right, you could be rich, you could be poor, you could be handsome, you could be ugly, you could be smart, you could be an idiot. It doesn't matter who you are, people always face obstacles in life, on their way to their goals.
Sometimes you have bigger problems because you are handling bigger stuff, a smart rich person will face an obstacle that is bigger, like merging of 2 companies that worth 100 million dollars but handling the deal properly, whereas some poor idiot may face something much simpler, but it’s always just one step at a time, solution is always fixing things one step at a time so that you would be doing a lot better in the long run.
There's no exemption when it comes to success in life then it would really be varying or depending on lots of factors whether you would be ending up on successful or would be completely be failing.
This is why we do keep on striving on doing things which we know that it would really be that relevant or helpful for us to have a better life.Always set goals and targets in life.
You should really be setting out and thrive to make it happen.
Life is indeed a puzzle and you cant really know on where you do go and if you dont do your best then you would be ending up on nothing.
