I was recently introduced by Daily UI by @Waldo which will help you to become a much better designer in 100 days. Every day (excluding weekends) you will receive an email from Daily UI with a design prompt.
You will interpret and design the UI element. Once you have finished, you can share it on Dribbble or Twitter tagging it with #dailyui and the number (#001). Users will then be able to give you feedback and you will improve your skills!
By the way, my personal site is: http://100daysofwebdesign.webflow.io/
Have a great day
