Conclusion
What I have learner, re-learned
Self motivation is key.
Keep moving forward, don't allow your self to get stuck.
Dream big but start with MVP.(Minimum Viable Product)
Fail fast and then iterate. Better to just get going, progress inspires while to much thinking can sometimes bog you down and drain you.
A expert is truly the one who have made all the mistakes and learned from them.
Do a prpoer documentation and gantt chart, helps to manage time and speed up the troubleshooting of any equipments.
