If taking 3 months off has rendered guitar less than interesting... May be you should take up playing the radio. If you can keep your focus, guitar will never bottom out! Music only gets better the more you play it. You get more proficient, you meet other musicians, the mysteries unfold and practice starts feeling like breathing. I have been playing guitar on and off for decades. As long as I practice, the experience only gets deeper and better. Hell music is one of the best reasons for being human!

If you travel a lot... get a travel guitar! I ski much of the winter and this frequently leads to motel rooms. With my travel guitar along I can easily practice any where. In fact I no longer dread waiting for planes in the airport. I just take a walk and find an unused gate. Then I put the travel guitar together, put on my headphones and wail away. Soon the airport is simply a faint anoyance at worst.
