First to market
The concept of “first to market” was created by marketers to achieve recall value. What they didn’t tell you is that in order for “success” you need to also have a good product in hand otherwise you will be forgotten when the next guy with the same kind of product comes along.
Being the first to do anything, or doing something different, unfortunately has become some kind of obsession in this age. We become discouraged when someone else does it first. I say screw that. Do it anyway. Your way is your way. No one is stealing from you. Get over yourself. EGO is the enemy clearly.
There is NO SUCH THING as ORIGINAL. God holds that card. Ideas are everywhere. We are influenced by everything we come upon. Consciously or unconsciously. All we can do is re-hash & add your own spin too it - innovate. This is especially so in the world of art & design. Do not be mad if someone else does something before you. Chances are that person also got “inspired” by someone or something they had seen curated on Pinterest/Tumblr/ Friend/ Family/ Observed etc. Everything you can think of has been done in some way of form. Nothing is original. Be happy instead to see your idea tested out and then get to work. Start creating, improve the idea and hopefully you will be the "first to market" the next time.
PEACE.
