I have been in this model building business for about 65 years. Every kit I have built has had some sort of a challenge to it. Some have been great and some have been a grind. It has put me on an ever increasing learning curve. But all have put a smile on my face when I was done and can look back at how I got there. I do this for me and it is a form of meditation of sorts after a frustrating day at work or just life its self. Modelling has taught me to calm down, be patient and look forward to the end result. Oh and don't discount all those tools you'll buy to make your job easier. I could build a space shuttle in back yard now.
