1) Be kind first, there will be plenty of time for all the other feelings later, if necessary.
2) There isn't "No," only "Not at this very moment," so never give up.
3) Pay yourself first (from day one), but use some of it to give yourself permission to never turn down new experiences.
Because I have changed careers twice (Football, Finance, Aviation), it made my "start in life" a bit delayed and made me more conservative about saving and not spending on some experiences we probably could have had. Now that I'm 53, I realize I could have spent a few more bucks on those experiences along the way and still been OK, but paying for college for myself and my kids, while buying a bigger, more expensive home as they grew, then having my company go bankrupt (50% pay cut and loss of pension) created a much more conservative me than I would have preferred. Anyone who knew me when I was younger or in college would laugh at the thought of me being conservative (small c) at all, but then I don't have the same Afro I had back then, either!
