Taking onto oneself the suffering of others and giving happiness and success to all sentient beings seems a heavy task, especially for a beginner in the practice. It might be appropriate to start out with smaller issues, like working with oneself to increase one's own well-being, increasing harmony in the family, open one's own mind to communicate better with other people or just finding more peace in doing the necessary daily chores.
Shouldering others' suffering and bringing joy and success to all living beings appears like a daunting task, particularly for someone just beginning their practice. It might be prudent to start with more manageable issues, such as improving one's own well-being, enhancing family harmony, broadening one's perspective to communicate better with others, or simply finding more peace in daily tasks.
