I know you heard this advice many times before, your outlook on life decides you actions and your actions define what you experience in life.
If you feel lonely you'll act lonely which in turn would be boring to other people and that makes you more lonely.
If you have negative thoughts and expect crises to happen they are more likely to happen because you Act according to the thoughts and the actions you take will influence the reactions you receive back from the world.
On the other hand, if you feel lonely but try your best and you know deep inside that you won't be in the future, you'll go out in the world and show your best side which people will love and then you get friends.
When I read the book "the secret" I thought it was full of bullshit, yeah i liked the idea but I didn't believe there are real forces that you send out to the universe and a response comes back from the universe.
Now I realize the meaning, I understand that the force described in the book is your attitude and the force that the universe responds with is actually the reactions you get to that specific attitude you displayed.
It's easy to forget this theory or even easier to convince yourself you're applying it while you aren't.
In the last 2 days I experienced how having a positive outlook on life can actually change your life.
