Perspective is everything. Don't let the world's standard of happiness and success be your goal. The world standard involves mostly material things. Let's not lose sight of being able to walk without assistance is a blessing, having all your bills paid is a blessing even if you don't have extra to splurge. Having some food is better than not having any. The list can go on but I encourage you to be thankful. Also it is ok to desire more for yourself as long as you're grateful for what you already have.
