All beautiful designs have ugly beginnings.

Onur Cobanli ཡིས་འགྲེལ་བཤད་བརྗོད་པ།
Design is hard, it is hard to come up with a good idea, it is hard to work on it, your initial drawings might not be as good or appealing, and you might under pressure or due to lack of time, and perhaps due to your lack of capacity and knowledge could come up with an ugly, bad, worthless design. Don't give up. Learn, and improve your knowledge and capacity. Acquire the skill to differentiate and understand what is good design, develop a discerning eye and beat your own ego. Reframe, revisit and reiterate your idea. Form it, mold it, shape it. Work on it, build upon it, make it better. You will succeed, without expectation.
