Current contemplation: To Lent or not to Lent?

I haven't been very religious for the past decade or so. I haven't been a practicing Catholic for much, much longer than that. I generally don't even think of myself as "Christian" anymore. I'm just a guy trying to follow the teachings of Jesus and figure things out.
However, I find myself considering a somewhat traditional observance of Lent this year. I'm not talking about a give up something/suffering for Christ thing, but I am trying to figure out some kind of daily practice to help me to grow spiritually.

Naturally, I am thinking about things like daily reading of the Bible or other writings of a spiritual nature (currently reading some early Merton stuff).
Regular mindfulness practice like meditation is something I need to get back to doing.
I'm thinking about maybe contacting several pastors or religious leaders to meet with them and discuss practices for spiritual growth and perceptions that they have towards it.

But I am also thinking that 40 days of purposeful exercise and healthy dieting is a worthwhile and mindful spiritual practice. Taking care of the temple is an area that my entire being has most definitely neglected for most of my life. 

I am hopeful that whatever I decide in the next few days will be something that incorporates both the physical and the metaphysical aspects of life and will give me something to continue beyond the 40 days of Lent.
Ash Wednesday is this week, February 18, and marks the beginning of Lent.

How about you?
Are any of my more religious readers planning any kind of Lenten observance?
Just wondering.
