Just this morning I got a chance to watch the 'Kerygma tv' of Bro. Bo Sanchez, and I heard a lot of useful advice. The topic was about what we focus on in our lives.
He said there's always the negative things and the positive things, but too often we focus on the negative side, instead of looking for the blessings, we magnify negativity. No wonder why we have a lot of problems, and no wonder where not living our lives to the full, because we don't see ourselves as God would see us. We choose to see ourselves, as... well, negative.
Here are the other things I got from watching:
You should say to yourself "I'm too blessed to be stressed."
If you want to be successful, stop focusing on your weakness, focus on your strengths.
You're weakness is not God's rejection, it's God's redirection.
Don't be too hard on yourself. You also have strengths.
