Financial health is super important to our well-being. If you are wanting to regularly make charitable donations and have the means, try adding it to your monthly budget.
Budgeting ensures that funds will be there when something important comes along that you want to support or so you can feel empowered to do so regularly.
Giving too much can literally exhaust our resources and no one would want you to give more than you have.
When you budget, you can choose the amount and either let it build or use it regularly. I have found it to help with intentionality regarding giving.
Give it a try!
