I am these days going through tough times, so I am reading a lot on Vastu/Feng Shui. Is there something I can do/correct which will give a boost to my career and wealth?

Have you read the book? If you have, I must really be a terrible, terrible writer!

But seriously; during tough times, the most rational of us could become superstitious – it’s a natural human tendency. All I can say is, if a change will make you feel better, go ahead and make it. Often, feeling better is a prelude to doing better. However, if it makes things difficult in any way: visually, practically or even financially, you’re better off waiting out the storm. This is a personal opinion and you’re welcome to think differently.
