If you don't plan what to do with your money, it will disappear via lifestyle inflation. Anytime you get a pay increase, decide how much will go to discretionary items and how much to save and invest. Make sure your are contributing enough to your retirement savings, save more on the side and so on. For your discretionary spending, budget accordingly, and beware of common lifestyle creep areas (cars, clothing, food, housing).

As for the "acts of kindness", it's a good thing to remain charitable, but do it wisely, and consider the impact. If you go and help in your local food bank you could be helping people who are really struggling to get by, whereas if you go to a bar and buy a round of drinks for everyone there, you may be popular for that evening, but you are not really helping anyone in the long run. When you do acts of kindness, ask yourself if it's for your ego, or for the other person's benefit. You could even consider doing it anonymously.
