Making growth plans : I try to balance my personal growth plans 50/50 in terms of what would be benefitial in the long term for my career as well + something just for my soul (e.g. For 2022 I plan to pick the next language to learn that could help me in my job + plan to learn to play piano just because I've always wanted to).
Staying motivated: For me tracking is key.
I have pages in Notion for habit / goal tracking, nothing beats the satisfation of a beautiful 30-day streak <3
