“It does not matter how slow you go as long as you do not stop.” –Confucius
The best way to improve at something is consistency. Even just a 1% improvement every day compounds massively. At the rate of 1% your skill in something will double every 72 days. In a bit over 2 months your skill in something could be twice from when you started.
The world of tech is ever changing. New ideas and paradigms show up all the time. Never feel like things are moving too fast for you. If you want to learn something and can commit to improving even just 1% in a day, you will soon look back and see how much you can do.
