Now, in a design field, only being a designer does not help. Technical knowledge of your design stream is required and his helpful. But, the solutions to our design problems come from our surroundings and by surroundings, it is everything! The architecture, flora and fauna, social causes, movies, plays, arts, crafts, the traffic lights, the sign boards, and literally EVERYTHING! Look around for inspiration, some of the basic things might have answers just around you! And you are yet unaware! As a designer, you should be well updated with the technology. It is not required that you should be a techie or a gadget freak, but you should know what is going on around you. What are the latest developments.
Read classic novels, stories; watch films of black and white era. Watch great movies like ‘Umrao Jaan’ and ‘Queen Elizabeth’! It is not that you should be all into your work. Yes, work is important! But it also equally more important to look around, to feel things, to watch great things, to witness historic moments.
Go out, take part in a play, watch a street performance, take a look at the international stores, go to parks, watch jewellery, go for car rallies, do adventure sports. These are going to be life changing experiences. Nothing is too great or too small. But everything is important, everything is individually great! It is important to know about everything, be it a village street performance or the Kingdom of Dreams. All can be great inspirations.
In the end, you are as successful in designing, as much as you have seen, as much as you have experienced ! Those many eye-openers you have, those many things you can do a research upon, make a product from.
In the end, it is all that you have experienced ! So, go out and see what is there in the world!
