Embrace yourself and do what you can to look and feel your best. Don't put on so many fashion trends that create a ridiculous style statement. Pick and choose what feels good, and flatters your own body.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
