Good for you pal!
I always try to act with the best interests of others.
Of course helping people is always good and if karma is real, certainly help us winnings points for it, besides, by helping people we can improve our surroundings and community little by little.
But, What worried me a little bit is the fact you say “always” and that didn’t sound very balanced for me. As I wrote on this article sometimes the best thing is actually saying “no”, the difficult is to know when we should help others and when we should invest our time in ourselves. But with wisdom we end up figuring out everything and growing as a person.
