Get out and shoot.

At first glance this looks to be the easiest thing that you will do.  In a way it is but at the same time it is the most important part of your growth as a photographer.  Like anything that you will do in life, practice is the best thing that you can do to improve.  Practice will lead to both  comfort and confidence, and these are important attributes to have as a photographer.  Your comfort and confidence levels will allow you to push yourself to higher levels and will allow you to attain the goals that you ultimately want to attain.  This leads to another important piece of advice, don't judge your work on the work of others rather look at your individual growth as a photographer, surround your self with like minded creatives.  In my experience photographers are more often than not willing to lend helpful advice.   

So get out there and challenge yourself to create a beautiful image.  Don't fall in to the pitfall of "likes" or "+1's" or comments, good or bad, if you love your images you will be happy.  Above all Shoot What You Love, Love What You Shoot
