the only people I know who are happy all of the time are my sister's 15 year old friends. and I assume it's because they are naive and/or not very smart and don't really think much into things most people I know have 'off' days, or get depressed occasionally.... that's just a natural reaction to life.
_________________ If theyre happy all the time ,theyre either really shallow.Or retarded Or have a terrible drug problem LOL Seriously tho , yes u can be. I think u need 3 big things going well to be "buzzing". eg work and purpose/ social life / serious interest / family or other half etc.
i'm not happy all the time, but i'm content. even when i'm feeling sad and miserable, it's just a surface emotion and i wait for it to pass on. but i'm deliberately stupid.
