You are right, the protestants don't pay much attention to Lent
No, actually, this is incorrect. The protestants do pay a great deal of attention to Lent. I was raised as a Lutheran and Lent begins on Ash Wednesday and lasts until Easter Sunday.
I was raised in the Missouri Synod and Lent was not viewed as a time of self- deprivation- it was a time to do more- a time of spiritual renewal. It was more about what you should do instead of what you shouldn't do. As kids we got involved in all sorts of extra giving activities during Lent.
Many of the Lutheran synods are becoming more Catholic in their practices, including giving up eating meat on Fridays during Lent, etc. Some Lutheran synods even go so far as to put ashes on the forehead on Ash Wednesday, similar to the Catholic practice.
