2. Find something useful to do with your commute (e.g audio books) or eliminate it. This could be a large part of your life and it adds up.
3. Marry the right person. Don't marry too young.
4. Fix your chronic health problems.
5. Understand and study nutrition.
6. Build relationships. This takes time.
7. Make things happen. Create things that weren't there before that other people participate in. Practice planning things in advance and executing on them.
8. Learn what you can from your parents before they go senile.
9. Have some sort of passion besides your job and passive entertainment. You will become a far more interesting person and attract interesting people.
10. Do not undercharge for your labor. Live well below your means. Don't work for or with jerks.
11. If something isn't working in your life, change something, measure and retry. Iterate. This is basically applying lean principals to everything. Don't get stuck with "good enough" and then it's a year later.
