Self-esteem is essentially about capacity, whereas self-worth is about value. Relatively good self-esteem is therefore, ultimately, of little help in the absence of self-worth. The pursuit of self-esteem, or attempts to boost it, can be premature and yield short-lived, superficial results
Self-love, or an internal recognition of one’s value, should ideally be anchored in an innate sense of oneself as valuable and lovable; it is not enough that it be predicated merely on being ‘good’ at this or that, or favoured/appreciated by this or that person(s) e.g. in recognition of our efforts/abilities in particular areas
We absolutely are, in a moral sense, ostensibly ‘the sum of our actions’. However, whilst this is how we may define moral identity, it is but one component of our essential being. Strong, sustainable self-worth reflects a deeper/broader knowledge of oneself that may centre on an appreciation of our core psychology or (manifest) ‘character’, but is not limited to our conduct or achievements e.g. within the domain of ethical behaviour
In focusing too heavily on self-esteem boosting endeavours one can place too much emphasis on building self-acceptance in relation to tokenistic, transient, external factors, (inadvertently) indulge vices like pride/egotism, and indeed potentially miss out on opportunities to bolster self-worth through introspection e.g. interrogating upstream processes, such as: "I am interested in self-improvement, and this is a valuable quality"
Every human being has value, and each has the capacity to love themselves – often what people need is to rediscover/internalise the sort of simple, infantile sense of unconditional love and security that we associate with early years parental love/support. Some find it helpful to seek to imprint this in the ‘parental voice’ of our psyches through things like meditation, mantras, and (self-)hypnosis e.g. "I am valuable; I am loving; I am loved; I am worthy of love"
Once we learn to love ourselves at this most basic level we can (safely and sustainably) move on to higher levels of self-awareness, self-knowledge, self-acceptance, self-love, self-worth, and critical self-improvement (which might otherwise be damaging/destabilising)
Let yourself begin to believe - you were created with unique, intrinsic value
