How to start a project

Hello Everyone!
Today i want to ask a question from you designers. I am a starter in graphic design scene. I want to ask that how you guys come up with new ideas for your designs? I sometimes stuck with creativity and cannot start a project because of that. Some people say me to google up what you're designing for innovation and then design something new from that.

I do this and i become able to design because of this strategy but i want to ask from pros that is it right i am doing? I am confused because i don't use my ideas from scratch. I take someone idea and make something new from that. For example; if i were to design a flyer for a I.T firm i will search for related flyers and then choose some reference and try to make some new design from that. Please help me about it, Thanks!

Regards,
