If someone were to tell me this just two years ago, I believe I would be far better off financially than I am now.Bank the good memories when they come. When you get the urge to put off an opportunity to enjoy yourself for tomorrow, remember that tomorrow doesn't come. It really doesn't.
Don't be afraid of failing even before trying because there's nothing that can be overcome. Really ... nothing.
Life is not supposed to be easy and struggle is very much a part of it. Don't woe the hard times as much and don't rely on the good times to last forever. Be expectant. Be flexible. Be accepting of your circumstances.
Seek help when you need it. Be independent when you can. Help others when you can and maybe they might do the same for you. Don't expect to rely on anyone but yourself ... but become the one others can rely on - so that you can continue to feel the joy of receiving. This creates a circle based on give and take.
And be happy but don't be afraid of sadness.
