Optimism can be extremely hard to achieve sometimes. Life gets tough, and we get negative; it happens!
Optimism begins in your head! If you THINK POSITIVELY you will be happier! Is it a scientific law? No, it's never been officially tested or anything... but YOU can test it! Try POSITIVE thinking for a week--even 2 days-- and see how you feel at the end of it. My guess is you will feel A LOT better!
In my opinion, when you have God in your life it's not that hard to be OPTIMISTIC. His love and grace FILLS you with JOY! When you have God it's a lot easier to see past the bad and have a POSITIVE ATTITUDE--knowing He has a plan and seeing His immense amount of love is enough to make anyone happy!
When you THINK with a positive attitude, you will ACT with a positive attitude. When you have the faith that you will succeed, you will not only act POSITIVELY, you will act more. When you ACT more, you will ACHIEVE more!
I'm not trying to say that being optimistic will be easy-- because that would be a lie! Life is hard, but you can enjoy it all. If you're optimistic there is ALWAYS fun to be found, and--with a little determination-- there isn't a thing you won't be able to accomplish!
Think. Act. Achieve.Through OPTIMISM and FAITH.
