Let's say you want to become a professional basketball player (LeBron status). That means you will likely have to spend years and years practicing, pushing yourself to get better. There will likely be days that you don't feel good, don't want to play, or lose games. You may have to sacrifice other things you want to do in order to spend time practicing.
These moments and situations may be distressing, and you may feel like quitting so that you don't have to deal with the stress. BUT, if you felt like the goal was IMPORTANT enough to you, you might choose to tolerate the distress, knowing it is only SHORT TERM, so that you can reach your goal in the LONG TERM.
You want to get a good paying job so you can support your family. That means you need to get a high school diploma, and probably some additional education like college or trade school. Learning new things can be stressful, boring, or difficult. There will be days when you don't want to do your homework or go to class or training.
Once you have your education, then you have to apply for jobs, and you will probably get rejected from some of the jobs you apply for. Finding a job is scary and stressful, and you may be so nervous that you don't want to even risk rejection. BUT, if it is IMPORTANT enough to you to get a good paying job to support your family, you will find a way to get through those boring and hard classes, and you will risk being rejected, because you know that you won't succeed if you never try.
