Start early

A lot of people tend to do things only when they are required to do so. So many opportunities that present themselves bare right under people's noses, but they never seem to realize it before it's too late. For example, if you know bad health is never good, then start changing, your lifestyle, your diet, your daily routine. Just do it before you realize that going on medication is the only way. That's just one example, and there are so many more things where starting early never hurts. Youths nowadays are just thinking about partying, and never about what's going to happen to them 30 years later. Sure, a lot of things can happen, but planning early saves you for the years ahead. Don't go all out on a specific plan, just come out with a goal, a to-do list, and a not-to-do list. Everything will change with time and experience, and the list will mature, as you will. In other words, save the rain before the drought.
