A quick google search: "We are called not only to abstain from luxuries during Lent, but to a true inner conversion of heart as we seek to follow Christ's will more faithfully."

"Lent is a time that offers us an opportunity to come to terms with the human condition we may spend the rest of the year running from and it brings our need for a Savior to the forefront. Like Advent, Lent is a time to open the doors of our hearts a little wider and understand our Lord a little deeper, so that when Good Friday and eventually Easter comes, it is not just another day at church but an opportunity to receive the overflowing of graces God has to offer."

"Lent is an intensely penitential time as we examine our sinful natures and return to the God we have, through our own rebelliousness, hurt time and again. Lent is also an opportunity to contemplate what our Lord really did for us on the Cross - and it wasn't pretty. But ultimately, the purpose of Lent does not stop at sadness and despair - it points us to the hope of the Resurrection and the day when every tear will be dried (Rev. 21:4)."

"Lent provides us an opportunity to examine our faith and to deepen our commitment to live a Christian life."

"Lent is more frequently seen as a time of solemn observance and preparation for the celebration of the death and resurrection of Jesus at Easter."

Once you understand what Lent is about, the description in the tweet is accurate and not at all weird.
