When you have a job, you are afraid of losing it. You have to go to work on time, do something that you don't like and in the end get a small salary. If you want, you can change everything, but I agree that is difficult to do. I believe in self-development and that any person can achieve any goal. Reading books is the best way to improve your mind and reach success. It depends on how much you want to achieve your goals. One of the most important things is self-discipline which is the decision to do something that you don't want to do in order to achieve what you really want. I work on the internet and have to get up early every day to do lots of work. I try to read at least 1 hour a day about online marketing, copywriting, psychology, cryptocurrency, etc. At first, it was difficult because I had a temptation to sleep a little longer, put work off until the next day, and other tiny problems because there was no job to lose.
