First time here and will make it as short as possible...
I believe so much in myself and in my potentials and I know that I am smart and intellegent... however I never managed to understand:

1. Why does it always seem that I am so unnoticed and unappreciated for all what I have?

2. Why am I single most of the time?

3. What are people's standards for attraction and why are shallow, selfish y idiots more attractive and happy all the time?

4. Is it bad to be good?

5. Why do I have to struggle for happiness and peace of mind on daily basis and get none at the end?!

AND MOST IMPORTANT:

6. Why is it that the more friendly and open-hearted you are to people they just are lousy and indifferent?

Only you can answer those questions because no one knows you as well as you know yourself.

Are you into reading? I could recommend some good uplifting stories that will help you to feel more positive about yourself.
