Optimistic attitude: there is a famous quote that goes, "Whatever you think, becomes you". it's very true, so keep a positive outlook always as that helps automatically helps us to go on with happiness and peace. All happens for the best, keep that in mind.
Socialise: We are social animals. Knowing that, it isn't easy to not to talk to anyone on this whole big ball so go out and socialise. Try talking to people around, Don't be hasty as it may show your desperation. Go slow and make friends.

So, try inculcating those and find out what you like best and try doing those. It'll bring a sense of happiness and help you to make yourself a better person.
