My spelling and grammar is not the best for what ever reason I don't know, however my maths is quite good also my memory for remembering numbers.
I find it a little frustrating with the spelling but would I swap it for the practical side (would I ****) I have from learning to braze at 12 to making and repairing a list of jobs longer than a roll of bog paper....
One thing I have noticed is some of the spelling and grammar police often turn to the practical people for small jobs they can't make themselves. Lots of people can knock up a decent post with good grammar and spelling but come the time to put up a set of shelf's or even a high seat lol
