Hope is the feeling, that the feeling you have is permitted.

We are driven by feeling pleasure and avoiding pain, and most of us spend time with the latter. Instead of being proactive and making choice that make us feel happy, we wait and then try and avoid the pain. The most important thing is to just deal with your emotions, accept them, feel them, rationales them, do something about them (if you can) and let them go. Don't block them out, everyone gets feelings of sadness and doubt but when you don't let them out they just eat away at you until there isn't enough left to hold them in and that explosion is worse then if you had just felt them at the time. Sometimes you need to learn how bad it feels at your worst to truly appreciate the great moments, don't let the sadness drain the happy moments from you, get rid of them so that you can appreciate every moment the way its meant to be experienced.

This often comes from emotional intelligence; self awareness, self regulation, motivation, empathy and social skills. understanding what is going on in your head and your heart. Understanding that meditation helps regulate the emotions, it is easier to deal with emotions when you are no irrational about them. Take an honest look at you reactions, are you actually comfortable in your own skin? Do you rely on other people approval? In ordinary life, take control by observing your emotions and taking responsibility for them, pinpoint exactly what you are feeling and discover why, and accept it of you are overreacting.
Learn to have emotional feelings but not let them control you. Not every negative emotion requires a panic, sometimes its just about accepting you are down but that right now there isn't anything you can do it about, you still have to find away to keep going and keep smiling. Pain is part of life and cant avoid it, you can only minimise it by accepting and dealing with it. All pain will pass. It won't and cant last forever.
Find situation for positive feelings. We are more reactive then active, we make the decision to let the world around us dictate out emotions instead of going out and feeling what we want to feel. Take responsibility for your feelings by just doing things, don't let others evoke your emotions do it yourself follow your dreams, and do what makes you happy.

Do things you love.
