Graphic design or any other discipline is difficult to do if you have not practiced it for a couple of years. For graphic design you need to have a lot of visual culture and have general knowledge about many fields. Designers have to be so versatile as to be able to make a logo for a sad funeral home and then another for a colorful ice cream parlor in the same day. It's not easy to focus and change subjects just like that. We have all gone through moments in which creativity does not flow as it should and we do not have good results in a short time, but in graphic design you need to be constant and have a lot of skill in handling software, which is becoming more complicated and comprehensive. .
I think we have to be patient and enjoy the creative process and be realistic in thinking that it takes time for training and work to have good results. Just put on some music and enjoy the process. In a little constant time you will see things differently. Greetings and cheers!
