Here are some tips that will definitely make you a better person in the long term:

First and foremost, always strive to do the right thing. Even when it’s hard. Even when it’s inconvenient. Even when everyone around you would do the opposite. You are more than likely to have an inner voice that tells you what the right action in a given situation is. You can choose to mute it with fears, excuses, popular opinions and so on. But if you choose to listen to it and follow it, you become a decent person.

Second, always try to improve yourself. No matter in what direction. Upgrade a skill, do sports, read a new book. All these things can help you grow as a person. Have high expectations of yourself without falling into the trap of over-perfectionism. Spend time with yourself and reflect what did you do well today and what could go better next time.

Third, find a way to be helpful to someone else. You don’t have to save everyone or fix all the world’s problems. But find a cause you care about and donate something to it (time, money, effort to create awareness, etc.). Whether it will be orphans, or endangered animals, or a nice elderly neighbor in need, it doesn’t matter. Just make sure that in some way you contribute to the well-being of another living creature.
