Particularly important, when you are new to design and making, is retaining a passion for what you are designing and making: this is crucial to facilitate success and is achieved more readily when you design things you love; not an imposed idea from someone else.
The joy of designing is showing the world your vision of beauty, the form something should take and how it should function. Not everyone will appreciate your vision, but who cares? It's your design! When you start designing things you don't actually like you are on a downward spiral.
Retaining a personal connection with the things you design, and make, is more important than most think; losing this connection will result in a distinct drop in the quality of your design.
You are not Alone
All that said, if you propose a design to something which appeals to you, I guarantee the design will speak just as loudly to others. Don't be put off if what you have produced isn’t something everyone likes: we are all independent beings and the world would be a very boring place if we all liked the same stuff!
