I am often late from work due to gambling. Did you ever lose time from work or school due to gambling?
Its an early sign of addiction maybe? If you know you have something very important to do and just set it aside to gamble is clearly an early sign of an addiction. Just don't let it take your job away, gambling for profit is good but don't let it take away the main source of your income.
I sure it's possibly the sign of addiction. OP should realize that and then start to reduce gamble.
Gambling for profit is just a temporary, it's just can achieved for a sometimes, not all time and not constant.
