I am wondering how I could “up my game”. While searching the internet, I read the following and it makes sense:

Asceticism in Modern Spirituality
While it’s true that asceticism – like many aspects of faith and human life – was abused at times in Church history, the legacy of asceticism is that of making saints. And it still has that power today in your own spiritual life. Why should you practice asceticism? Here are some powerful reasons.

1. Asceticism combats habitual sin. If you struggle to control your desire for something you tend to abuse (food, drink, sex, comfort, etc), practicing self-denial is like building your spiritual muscles against it.

2. Asceticism builds the virtue of temperance. Temperance is the virtue that balances our desires for physical goods. When our desires are out of balance (a condition of Original Sin called “concupiscence”), we need to reset the balance with self-denial.

3. Asceticism protects you against the excesses of the culture. Like the culture the early Christians lived in, our modern culture has deified entertainment, luxury, and physical pleasure. While Christians can give lip service to resisting these temptations, the truth is that we’re immersed in this culture and it’s difficult not to be transformed by it. Asceticism helps us to set our hearts on the greater goods and to resist laxity of heart and open our hearts to be transformed by grace.

4. Asceticism moves our hearts away from selfishness. We live in air-conditioned comfort, even in our cars. We get used to having entertainment literally at our fingertips. Everything in our lives is built around convenience, entertainment, and comfort. Even the largest hearts among us can become lax when we get used to being comfortable all the time. Self-sacrifice prevents our modern lifestyle from sinking too deeply into our hearts. This was the reason Saint Francis required his brothers to serve the poor by living among the poor and why Dominicans also took a vow of poverty. Monastic orders at the time lived luxuriously and religious men and women were losing the true sense of their vocation. The same principle applies to lay people living in the world.

5. Asceticism can be an act of love. Like the first Desert Fathers and Desert Mothers, we can offer our self-sacrifice as a token of dedicating our complete lives to Jesus. Asceticism can exercise the theological virtue of charity. It can be an act of love for God, and we can also offer our voluntary suffering for the salvation of souls, making it an act of Christ-like love for our neighbor.

Asceticism plays the same role for us today that it did for the early Christians after the Edict of Milan. It shapes our hearts away from concupiscence (sinful desire) towards God and selflessness. It exercises the selfless love of charity. Of course, we want to avoid the excesses and abuses that have given asceticism a bad name (think of Hollywood’s portrayal of the scrupulous Catholic whipping himself bloody with a Cat-O-Nine-Tails in front of a crucifix all night). But properly used, asceticism is an invaluable tool in our spiritual toolbox.
