To be happy and enjoy your life, you should do what you love in life and reduce the amount of stress. The less you're being nervous, the healthier you are. Try to think positive and overcome all of the obstacles coming in your way. If you're having a hard time, don't give up and ask your family or friends for help. Don't let the routine take control over you, make sure you have enough time to rest and occupy yourself with different hobbies or things you love.
