Re-inspiring and challenging your photography is always a great idea. Choosing to do different things or rinse and repeat until you obtain your goal (grinding), can be very effective. However, it is the general thought patterns and approach to this that can drastically effect your own personal output.
New Years resolutions are something I consider to be throw away ideas or thoughts that temporarily make people feel like they are actually achieving something. An almost ‘cheat’ to oneself. But the only real way to do this is to make a life change. Add something into your routines.We are very routine and pattern focused as a species, so once we get used to doing things over and over, it can become second nature. A New Years Resolution is another form of GAS (gear acquisition syndrome). The temporary fix or high you get when you have or do something new. It has an almost instant gratification impact, then will slowly fade in a short period of time. This is because without the proper dedication or means behind it, it is exactly that: An instant gratification. Something to give you a temporary boost.
Now, there is not necessarily anything wrong with this, in fact, I am quite guilty of it myself. However, if you truly want to make a difference, you will need to prioritise and introduce these things into your routines.
In regard to photography, this could be as simple as make sure you have a camera on you when you go out. Having the tool there allows you to start doing photography whenever, and a more compact mirror less camera will allow you to do this. Another might be, always keep a tripod in the car. Or plan several big photography specific trips throughout the year. Something where you know you will be inspired and shooting a lot more.
New equipment is nice, and to a certain extent can inspire, but make sure it is relevant, rather than just an expensive toy for the sake of it. Something you know you will need or have wanted at certain points to obtain a certain sort of photograph. Once you have it, you can apply it to one of the ideas above.
I am going to keep this one short and sweet. Prioritise and add it into your routines. That is the best way to back up any sort of resolution or ideal you have managed to convince yourself will happen just because you like the idea of it. Grab your cameras, and get out there! - Sly.
