Being unsuccessful is relatively easy. At least it is at first. Laze around, do little to no work and spend money you don’t earn or have. the consequences mean it does get much harder as the months and years go by though.
Building up your success habits is another story though. Eating less and better food takes discipline. Exercising or going to the gym takes discipline and it can be hard. Studying is rarely easy. Same with doing your work, dishes, and laundry. Saving and investing is also quite difficult near the start.
There are a lot of things you need to do to be successful. The sooner you get each one under control, the better off you’ll be!
