I like the sort of 'nothingness' of the jeans and the T-shirt. I feel that's about as close as I can get to the future because it seems like something so old that will always be, so I feel it's a safe bet for the future.
To be a light to others you will need a good dose of the spiritual life. Because as my mother used to say, if you are in a good place, then you can help others; but if you're not well, then go look for somebody who is in a good place who can help you.
