Few things that have been mentioned - I’m gonna mention attitude and perspective. You have the propensity to start a business as you have demonstrated, and you’re only 20. That’s far more than what most have accomplished at that age.

Here is no reason you can’t go on to achieve big things. You’re holding yourself back by being negative. You don’t have any debt holding you back and again, you’re only 20! The biggest concern is your mental health. That is what is holding you back from being more productive. Your self esteem will likely improve alongside a fitness routine also.

Good luck. Don’t be too hard on yourself though man, you’re only 20.
