Great art takes time. Many artists look back with regret at the time that they abandoned a project that was not advancing quickly enough, or that it took too much time from their life. Many of these artists also recognize that their failure to complete the project was due to lack of motivation, time, and effort.
Rejection is normal. Negativity will always be part of an art form that requires subjective analysis. You cannot let yourself be affected by this negativity. Instead when faced with rejection, take a moment to be proud of yourself for courageously exposing your art for all to see. Always remember that only those who can push past rejection can have a chance at being successful.
Always be Unique. No artist in the history of the world has ever left a lasting legacy by making the same art like everyone else. Of course, this does not mean that one has to create a unique style of the bat. Many popular artists tried out the most common styles, which gave them the ideas to create something special and new. If you want people to remember your name, then you have to start making art that is one of a kind.
Always Keep Learning. This applies to any type of job that requires some extent of creativity. It does not matter if you are a writer or a graphic artist, if you do not stay on top of trends and updates, you will soon be left behind in the industry. Remember that there is always someone willing to go the extra mile and learn what you are too lazy to attempt, and that person will have the upper hand when push finally comes to shove. To survive you must keep moving.
