Loser?

I received a text message from a former staff and it says “Loser!Haha!” I was taken aback. Am i really a loser?
At the age of thirty, I haven’t done anything significant in my life. I had a good paying job but I gave it up, because I was too stressed with the way things are going in the company. A year after, I was offered simultaneously with two jobs. One offers a higher salary and the position is already top management, the other is supervisory and the pay is meager. And guess which job I chose!. I chickened out. I was not confident with my ability so I settled with the less glamourous and low paying job. And the job I chose cost me an enemy, who calls me a loser without second thoughts
I’m beginning to think that indeed, I am a loser.

BUT I am NOT!
