Start with a simple website/ web design
When you are a beginner, then you should be aware of your limitations, in order to overcome these step by step. This is why we suggest you to be patient and start with simple web designs.
Simplistic web designs are also very trendy these days, as we live in the days of minimalism, so there is no issue if you decide to start with the basics.
There are several easy to do templates available specifically for web designers. Web design blogs have tons of advice for beginners, letting them know on how to get started.
Basics will create the base of knowledge you will need for later on, therefore stay patient and keep on exercising. If you feel you are unable to do anything, go ahead and try to look for a resolution with the help of a mentor, boss or an online community.
