My first solo nav, back in my teens, instructor sends me out, wx is scattered showers with plenty of separation between the clouds, heaps of blue sky, I'm young and keen as mustard. 5 minutes into the flight I find myself in IMC. Learnt to respect Mother Nature that day and learnt the meaning of DO NOT RUSH. Also learnt that proper training as well as remembering words of wisdom is a really good idea. Saved my bacon that day.
