End of the day i think its all about doing something you like. Doing a business which you dont have interest in will not take you anywhere
It's very situational.
If you don't like what you do but it's going to be the best mean of your choice to survive and make a decent living. You can always go through with it, study, and learn as you go through the process, and later on you will start to like it.
But if it doesn't work, you're right. It won't be long then you are the one to start giving it up.
The option is doing your passion but minimal with profit.
High profit but doing what you don't like.
But the luckiest people are doing both, what they like at the same time earning decently.
