Be wary of people who make good propositions but lack any morsel of professional composure.
Dear Client-san, you lose any shred of credibility when you say "I have already replaced you" or "I hated your designs" or even "the reason I didn't answer the questions you had is because I was too busy" despite bombarding me with emails everyday, always replying to my emails within minutes (though conveniently glossing over the important questions I had), and after you just
spent the last several hours/emails trying to bribe me with tens of thousands of dollars to continue. Lol.
I feel a mountain of relief knowing I freed myself from that ridiculous, unprofessional situation. Have fun falling on your face.
I realize 99% of you will have no idea what this is in reference to, but people accepting commissions, be careful of who you do business with when it comes to long-term projects. Most of the time it is amateur projects that have no real potential or will be of very little benefit to you (no matter how much they promise it will be "the greatest gift to mankind" or how much profit they will "most definitely make").
Please don't be afraid of commissioners, I rarely encounter 'bad' ones, but it's always to your benefit to be cautious and if something doesn't sit right with you... get yourself out of it asap before you invest any more time/effort.
