Practice for at least 10-15 minutes every day.
If you do this, I guarantee you'll improve. It's a skill which requires practice to level up and maintain.
Meta: Why are you asking HN about this? I mean no offense, genuinely not understanding how you think about this problem, and I'd like to better understand your reasoning. In the back of my mind I wonder if you're just karma farming. Not that anyone has ever admitted it yet, IME.
Few tips :
- Analyze what you need to improve
- Trace examples (if you google for example "writing practice sheets" you'll find tons)
- Slow it down, as slow as you can, only speed up slowly later
- Practice things you struggle with in isolation, for example certain letters, or letter combinations
- Try to find joy in your practice; for example setting goals, maybe get creative and try some calligraphy? maybe combine it with journaling? something to motivate you
- Prefer shorter daily practice sessions over longer spaced out sessions
- Be patient and be mindful that it takes time, especially the beginning, don't give up too early
Not that different from learning an instrument btw!
