Sometimes it helps to be happy with smaller things, if you're in a big rush for big happiness you could be in for some unpleasant surprises like drug addiction, failed relationships, etc etc Better to be happy with what you have, and thankful for the wisdom you have, rather than hell bent on making things "better". Suffering is all in your head, so to speak, what is suffering to you might even be happiness for a more enlightened person, learn to be grateful you have this precious body to attain wisdom and knowledge, and every time you think how bad it might be for you, think of how much worse it could be. At least thats how I try to look at things! Hope its some help.
18 years ago I made one of the most important decisions of my life and entered a local Cambodian Buddhist Temple as a temple boy and, for only 3 weeks, an actual Therevada Buddhist monk. I am not a scholar, great meditator, or authority on Buddhism, but Buddhism is something I love from the Bottom of my heart. It has taught me sobriety, morality, peace, and very importantly that my suffering is optional, and doesn't have to run my life. I hope to give back what little I can to the Buddhist community that has so generously given me so much, sincerely former monk John
