We all have friends who are constantly bragging about how busy they are and why they have been missing in action lately, but frankly, I don't consider being "too busy" an excuse to not maintaining a relationship with people, even if it's a brief two minute phone call or message every month or so. I personally consider myself a busy person because I partake in a lot of activities. Alongside my full time job, I also do freelance work, run several personal projects, and volunteer, but I make sure to always have time to hang out with friends, socialize and send personal emails/messages checking up on them, even if they are far away.
People always complain about not being able to "find the time", but the truth is, it's not about "finding time" it's about "making time". Making time helps you manage, organise and prioritise. If you're constantly overwhelmed, maybe you shouldn't be taking up so many activities. The fact that we are constantly connected (internet is widely available, smartphones, tablets, laptops, etc), gives people no excuse to not respond to their messages and not keep in touch or send off a brief "hello, how are you?" If you find the time to check your Facebook account, write on someone's wall, post a few links, photos and comments, it's likely you check your emails and your cell phone messages. And if you have the time to do everything it is people do on Facebook, you surely have the time to respond to a friend who has been attempting to reach out to you for awhile with a simple message.
What shocks me is that most people who claim to be unbelievably busy are ones who are in school (don't get me started on people in relationships who choose to seclude themselves in a box, destroy all their friendships and then when their heart is broken, attempt to find a friend to lean on and can't find one). I went to university, and while in school, I worked, volunteered, and participated in countless students activities. I understand that some majors require more work than others
and that constant studying is a priority, but if all you're doing is school, then there really is no excuse. I understand your priorities, but one should never forget to maintain relationships with others.
There's no such thing as being too busy. The fact of the matter is, people like to pretend they are busier than they actually are. They check their phones constantly, attempting to show others how busy they are but in reality, they are just playing a silly game on their iPhone.
