We don’t even notice, how our lives and minds are taken by several bad habits bit by bit. We got used to certain feelings and reactions and don’t notice thier harmful effect. Try to get rid of some of these and you will notice the Sun shining brighter.
Stop spending time with the wrong people
There is one thing you should understand. The world has billions of people, and among them there are enough of those, who can become really close friends of yours. You shouldn’t waste your time on people, who make you feel used, bored or not good enough. The same rule applies to those, who are not willing to share their time with you. Don’t try to be with anyone in order not to feel lonely. As long as there is free space for your kind of people to appear in your life, they certainly will. 
Face your problems
There is nobody, who can deal with your problems better than you. Stop hiding and look for a way to find the best solution for the situation. You will see, how much easier it will be for you to live without the need to think about it every now and then.
Be a little bit selfish
Of course, it doesn’t mean to become an egoist. This tip means only, that you should never forget about yourself, while you’re helping others. Help should never be a burden; it should be done wholeheartedly and is not supposed to make you suffer. Being a little bit selfish also means to always be yourself and love yourself, not trying to act like idols and celebrities. You are a unique person, and you are precious just the way you are.
Remember, that life is not a contest
Don’t try to prove to others, that you are better than them. The only person you should compete with is you. Your ultimate goal is to be better than you were yesterday. You should also stop feeling envy, as you possess enough skills to keep on the way to your aim. If you don’t let yourself stop, you will see better results soon.
Stop pitying yourself
This feeling is only a comforting thought, that lets you stay where you are and not improve without feeling guilty for it. Life is not always easy, and bad things happen to everyone. What makes a difference is the way people deal with problems. Some feel offended and unhappy; they give up easily and feel stuck later. Others find the power to move on and overcome any difficulties. You certainly don’t want to be the first type. 
Don’t try to make everyone like you
It is impossible for everyone to like you, as what one person might find lovely and nice, the other one will consider annoying. You should keep on being yourself and remain positive. Stop worrying, as it doesn’t help you to be more productive in any way, but can ward you off the joys of life. Ask yourself – will these people matter in a year? If the answer is “no”, there is no need to worry at all.
