Do not spoil what you have by desiring what you don't have. Remember that what you now have was once among the things you only hoped for.
In the end, people will judge you anyway. Don't live your life impressing others. Live your life impressing yourself.
Your happiness is the most important aspect of your life. Happiness gives you life, energy, and motivation. Being anything less is a waste.
Think good thoughts. Say nice things. Do good for others. Everything comes back.
