If you are suddenly feeling like you are down in a rut or just don't have the energy to get up and go do something, then you may be suffering from a few issues that can be easily solved if you simply knew how to motivate yourself. There are a lot of self help books and software that just want to take your money so I'm not going to get into any of that. There are a few simple ways to get yourself off the couch and back into the job market or wherever you really want to go in no time. Business cards are a plus, but it takes a lot more than that to get you back on track.
When I say advertise yourself, it can mean many things. From dressing in a professional and uncomfortable manner at least a few times a week can actually boost the way you think of yourself in a very positive way. People who look good will often have higher self-esteem because of the way they view themselves. So if you find yourself in sweatpants during the middle of the day, it might be time to switch to slacks at least during weekdays.
The way you dress is just one way you can give the wrong impression about what kind of person you are. The way you speak and the bad habits you bring to the table when it comes to vernacular can definitely change the way people perceive you. If you constantly make grammatical errors on emails or in the real world, it can negatively affect the chances of them enjoying your company. One silly sentence can turn someone from a valuable friend to someone who secretly disrespects you. These bad habits are a little difficult to fix, but a few weeks of watching your speech and you should be able to get rid of all your bad habits especially if there is someone else there to catch you in the act.
If you are still getting nowhere in your life, it can be helpful to make a business card for yourself and design it so that it reflects what you hope to accomplish in the next few years. Print out a bunch of these and hand them out to people who don't really know who you are. You will realize that you will be able to fulfill your dreams before you know it.
