Let's think today in a positive way, like any other day.
Everyday you wake up, try to see what surrounds you in a positive way, if that means setting goals, go for it. Get a piece of paper, a pen, and right what you really want to achieve.
Think about a brainstorm:
-Your goal
-Why is that you goal?
-How can you achieve it?
Sometimes you feel insecure about everything because you don't really know what is going to happen and if everything is going to succeed as you think is going to happen. It is very easy to take the easy path, the path in which you can walk smoothly and without problems, but always achieving a goal, makes you a much more experienced and mature person, since it makes you be knowledgeable about never giving up, and never leaving your dreams.
