M&S gives you the freedom to be yourself. If you are genuinely motivated by a challenge, there’s nothing to stop you or hold you back. I would pass on the same advice I was given. Seize the opportunities. Share your ideas. Try things out. If it works, great. If it doesn’t, learn from it. This is the way we move forward as people – and as a business.
